Co2Nx/nitrogen-doped reduced graphene oxide for enzymeless glucose detection

Abstract

Co₂N_x/nitrogen-doped reduced graphene oxide (Co₂N_x/NG) is synthesized by electrostatic co-precipitation of Co and rGO followed by high-temperature nitridation, which can serve as an efficient catalyst for sensitive glucose detection due to the unique electrocatalytic property of Co₂N_x and synergistic effect between Co₂N_x and N-doped rGO.
